More specifically what I was referring to was the fact that traditionally HTTP 
failover with round-robin A records is very unreliable; every client can act 
differently. You really need to be doing anycast as well to ensure those 
records are always available which adds additional architecture complexity that 
the project may not have the resources to throw at. GeoDNS also adds a layer of 
complexity, but as it turns out there are members of the project with extensive 
experience running it. SRV would give us very simple, cheap, reliable failover. 
It seems we do have some blockers, though.

The good news is that we fully control the client. Hopefully we can just work 
around these issues.
